A vehicle control system increases the travel distance of a vehicle by inhibiting reduction in the SOC of a battery even when the output of an engine is limited. The control system is characterized by comprising: an electric motor that drives a vehicle: an engine that drives a power generator that generates electric power to be supplied to the electric motor; a battery that is configured to be chargeable by the power generator and that is electrically connected to the electric motor; and a controller that controls the electric motor.

Devices, systems, and methods are provided for enhanced obstacle detection. A vehicle may detect a neighboring vehicle traveling on a first road in a first traffic direction in a vicinity of the vehicle. The vehicle may collect data associated with the neighboring vehicle using one or more sensors of the vehicle. The vehicle may determine a status of the neighboring vehicle at a geolocation of the neighboring vehicle based on the collected data. The vehicle may determine that a first road anomaly occurred at the geolocation based on the status of the neighboring vehicle. The vehicle may set a first flag indicating the first road anomaly. The vehicle may determine to take a first action based on the first flag.

The invention relates to a method of operating a vehicle (1) comprising at least a first vehicle retarding subsystem (3; 5; 13) controllable to retard the vehicle (1), and processing circuitry (15) coupled to the at least first vehicle retarding subsystem (3; 5; 13), the method comprising the steps of: acquiring (S10), by the processing circuitry (15) from the first vehicle retarding subsystem (3; 5; 13), at least one value indicative of current energy accumulation by the first vehicle retarding subsystem (3; 5; 13); and determining (S11), by the processing circuitry (15), a measure indicative of a retardation energy capacity currently available for retardation of the vehicle (1), based on: the acquired at least one value indicative of current energy accumulation by the first vehicle retarding subsystem (3; 5; 13); a predefined model of retardation energy accumulation by the first vehicle retarding subsystem (3; 5; 13); and a predefined limit indicative of a maximum allowed energy accumulation by the first vehicle retarding subsystem (3; 5; 13).

The invention relates to a method for controlling a vehicle (1) comprising an electric powertrain, an energy storage system (ESS), regenerative braking functionality and cruise control functionality, wherein the cruise control functionality is configured to maintain a set cruise control speed of the vehicle during downhill travel by applying the regenerative braking functionality, the method comprising: obtaining (S11) a tolerance limit for an allowed increase in energy consumption caused by non-use of regenerative braking during downhill travel; obtaining (S12) information relating to an upcoming downhill road segment (DRS); based on the information relating to the upcoming downhill road segment (DRS), setting (S13) an allowed overspeed, caused by non-use or reduced use of the regenerative braking functionality, wherein the allowed overspeed exceeds the set cruise control speed for the upcoming downhill road segment (DRS) and is set based on the tolerance limit; and in the upcoming downhill road segment (DRS), controlling regenerative braking and rolling of the vehicle based on the set allowed overspeed, thereby reducing or preventing regenerative braking during the downhill travel.

A hybrid vehicle control method for a hybrid vehicle is provided for a drive system including an internal combustion engine, a generator that is driven by the internal combustion engine, and a battery that is charged with electric power generated by the generator. A target power generated by the generator is set and the target engine output is calculated for the internal combustion engine according to the target generated power. The air density in the environment in which the vehicle travels is detected. The target engine output is corrected based on the detected air density with respect to the decrease in air density, and the generated power of the generator is made to follow the target generated power. The execution of air density correction is permitted or stopped depending on an operating state of the drive system.

In some examples, a controller receives measurement data from a sensor on a vehicle, determines, based on the measurement data, a condition of usage of the vehicle, and selects a parameter set from among a plurality of parameter sets based on the determined condition of usage of the vehicle, the plurality of parameter sets corresponding to different conditions of usage of the vehicle, where each parameter set of the plurality of parameter sets includes one or more parameters that control adjustment of one or more respective adjustable elements of the vehicle. The controller causes application of the selected parameter set on the vehicle.
